The engineers at H2W have developed their most compact voice coil positioning stage to date. The customer for this stage requested that it fit within a volume of 1.6 cubic inches (40 cubic mm) cube volume. The application required an ultra-compact stage due to space restrictions in their auto-focus mechanism.
The voice coil positioning stage (VCS02-001-CR-01-MC) is a closed loop system that can be used for high-speed positioning and auto-focusing applications. The stage is driven by a NCC type actuator (NCC02-07-001-1R) and is guided by a precision linear crossed roller bearing. The voice coil has a 0.20" [5.1 mm] stroke; generates 0.26 lbs [1.16 N] of continuous force and 0.78 lbs [3.50 N] of peak force. It includes a 1 micron resolution magnetic linear encoder. Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.
